SPECIFICATION forming part of Letters Patent N 0. 670,824, dated March26, 1901.

Application filed March 2, 1900. Serial No. 7,120. \No model.)

To all w/wm it may concern.-

Be it known that I, LEWIS E. THOMPSON, a citizen of the United States,residing at Mo- Kinley, in the county of Adair and State of Iowa, haveinvented certain new and useful Improvements in VehieleWheels, of whichthe following is a specification.

This invention is an improvement in spokesockets and spokes forvehicle-wheels; and its object is to so construct the parts that greaterstrength will be imparted to wheels embodying this invention. 7

IVith this object in view the invention re sides in providing a hub witha rectangular socket of greater width than those usually employed havinga slight incline at its outer end and a greater incline at its innerend, a spoke with a tenon of greater width than .those usually employedin articles of this character having a slight incline at its front endand a greater incline at its rear end, and in providing the spoke-bodywith a slightlyinclined straight side and the opposite side beingstraight and inclined at a greater angle to the longitudinal centerthereof, so that the strain on the wheel will be next to the inner sideof the hub, the inner end of the spokebody being rectangular incross-section and inclined on all four sides to a round outer part.

Heretofore it has been found that when an abnormal load is supported byheavy wagons the spokes of the wheels thereof have a tendency to springaway from the hubs, and the wheels are then termed dished. By the use ofmy invention the liability of this inconvenience is reduced to aminimum, inasmuch as the strain is properly proportioned on either sideof the longitudinal center of the spokes, thus causing the wheel, ofwhich they form the essential parts, to withstand the extra strainincidental to an abnormal weight.

7 The peculiar construction and arrangement of my invention will befully described hereinafter, recited in the claim, and illustrated inthe accompanying drawings, in which- Figure 1 is a section through awheel constructed in accordance with my invention, and Fig. 2 is adetail perspective view of a spoke.

In carrying out my invention I provide a hub 1 of the standardconstruction containing a sleeve or box 1 which surrounds the spindle lof an axle 1. A series of spoke sockets or mortises 2 are cut from saidhub and extend nearly the entire thickness thereof, so as to receive theextra wide tenons 3 of the spoke 4C. The spoke-sockets are formed withslightly-inclined outer ends and greater inclinedinnerends. Thesetenonshaveslight inclines 3 at their front ends and greater inclines 3at their rear ends and have parallel sides and are slightly narrowerthan the spoke proper, so as to provide shoulders 5 and 6, abuttingagainst the outer wall of said hub, whereby greater strength isprovided. The spoke sockets or mortises are not cut entirely through thehub, but only to a certain depth, so as to leave integral parts 1 of thehub between the spoke sockets or mortises and the sleeve or box.

It will be noticed that this spoke is comparatively flat from its tenonend to about midway between its ends. From this point to the enddesigned to enter the felly it is round. In constructing the spoke inthis manner I provide a straight side 7, slightly inclined, which inpractice will face the outside of the wheel, while the other side of thespoke is inclined at a greater angle, as at 8, from a point intermediateits ends to the tenon end. By this construction, the side 8 being at agreater angle and inside of the Wheel, the strain is distributed on eachside of the longitudinal center of the spoke and tire, so as to equalizethe strain and thereby remove the liability of the wheel becomingdished. It will thus be seen that While the Weight of the wheel is notmaterially increased greater strength is provided, as well as a Wheelwhich will remain true and which will track properly.

Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent, is

A vehicle-wheel comprising a sleeve, a hub in which the sleeve iscontained, formed with a series of radial spoke-sockets, leavingintegral parts between the sockets and the sleeve, each socket having aslight incline at its outer end, a greater incline at its inner end andparallel sides, and a series of spokes, seating rectangular shape incross-section and exon the integral parts of the hub, each spoke tendinginto a rounded outer part.
